省市地区选择在各类项目中都可能要用到, 想要联动又刷新, 想只存地区代码又想显示方便, 还想要开发和部署简便...于是我的 DistrictDropDownList和 DistictLabel 应着全国人民的心声面世了 ^o^;; 这两个控件是本人2005年在公司开发一个网游交易网站时顺便做的. 在2006年试用Atlas时发现WebResource的好处后对控件做了改良.
DistrictDropDownList 的特点: 客户端使用JS+XML实现省市联动, 在IE6/5, FF2上测试通过.
DistrictDropDownList 和 DistictLabel 共同特点:
1. 主要属性是Code, Code是个Int32的值, 用于存储全国行政区划编号. 这样用1个变量(字段)就能存储省市(县)区3级别的信息.(区级用得少,所以这个版本没包含)
2. 行政区数据信息以XML格式嵌入在控件DLL中, 数据整理自中国国家统计局行政区划代码2006年12月31日版.
2. 在VS里即拖即用,呵呵
